Description

Es sind Rollfilmkameras bekanntgeworden, bei denen das Bild auf einer Mattscheibe einstellbar ist. Bei einer solchen Kamera ist der Film derart vierschwenkbar, daß in der abgeschwenkten Lage ein Mattscheibenbild der Betrachtung zugänglich ist. Von einer solchen Kamera geht die Erfindung aus und hat zur Aufgabe, den Aufbau möglichst zu vereinfachen: Erreicht wird dies dadurch, daß erfindungsgemäß das gesamte Filmgehäuse von der Kamera nach außen abschwenkbar und mit einer zur Filmebene rechtwinkligen Mattscheibe fest verbunden ist, die beim Abschwenken des Filmgehäuses aus der Kamera in die Einstellebene übergeführt wird. Dank dieser Anordnung braucht die Mattscheibe nicht federnd gehaltert zu sein, und die Spulen können fest zueinander angeordnet sein. Ein Ausführungsbeispiel des Erfindungsgegenstands ist in der Zeichnung dargestellt, und zwar in Abb. r in der Aufnahmelage des Rollfilmteils und in Abb. 2 bei der Mattscheibeneinstellung.Roll film cameras have become known in which the image is on a Focusing screen is adjustable. With such a camera, the film can be swiveled in four directions, that in the pivoted position, a screen image is accessible for viewing. The invention is based on such a camera and has the task of constructing To simplify as much as possible: This is achieved by the fact that, according to the invention, the entire The film housing can be swiveled outwards from the camera and is at right angles to the film plane The focusing screen is firmly connected when the film housing is swiveled away from the camera is transferred to the setting level. Thanks to this arrangement, the screen needs not to be resiliently supported, and the coils can be fixed to one another be. An exemplary embodiment of the subject matter of the invention is shown in the drawing, namely in Fig. r in the recording position of the roll film part and in Fig. 2 with the focusing screen setting.

Die Gesamtkamera besteht im wesentlichen nur aus zwei Hauptteilen.The overall camera consists essentially of only two main parts.

Der eine Hauptteil ist durch das Spulengehäuse a gebildet, das mit der rechtwinklig abstehenden, starr daran befestigten Mattscheibe d' im Gelenk c mit dem anderen Teil, dem Lichtschacht b, verbunden ist. Beim Gebrauch klappt man zuerst den Apparat auf, stellt scharf ein, klappt wieder zu und belichtet nach Freigabe des Films.The one main part is formed by the coil housing a, which is with the right-angled, rigidly attached focusing screen d 'in the joint c is connected to the other part, the light shaft b. When you use it, you work first open the device, focus, close again and expose after approval of the film.

Im geschlossenen Zustand ist der Apparat wie die üblichen Kameras verwendbar.When closed, the device is like the usual cameras usable.
